The radiomic nomogram for lung adenocarcinoma prediction. a Radiomic nomogram developed for the prediction of lung adenocarcinoma, which incorporates radiomic signature, internal composition and margins of nodule. Plots (b) and (c) present the calibration curves of the nomogram in the training and validation datasets, respectively. The calibration curve illustrates the calibration of the nomogram in terms of the agreement between the predicted risk of malignancy and the observed outcomes of malignancy. The 45°diagonal line represents a perfect prediction, and the red line represents the predictive performance of the nomogram. The red line has a closer fit to the diagonal line, which indicates better predictive accuracy of the nomogram
